Error running DCE example

[G2Dom]

Hi,

Any ideas on this error when trying to the DCE examples from:

git clone https://source.codeaurora.org/external/qoriq/qoriq-components/dce
git clone https://source.codeaurora.org/external/qoriq/qoriq-components/qbman_userspace

I run to setup:

  sudo restool dprc create dprc.1 --label="DCE test dprc"

  sudo restool dpio create
  sudo restool dpio create
  sudo restool dpio create

  sudo restool dpdcei create --priority=1 --engine=DPDCEI_ENGINE_COMPRESSION
  sudo restool dpdcei create --priority=1 --engine=DPDCEI_ENGINE_COMPRESSION
  sudo restool dpdcei create --priority=1 --engine=DPDCEI_ENGINE_COMPRESSION

  sudo restool dpdcei create --priority=1 --engine=DPDCEI_ENGINE_DECOMPRESSION
  sudo restool dpdcei create --priority=1 --engine=DPDCEI_ENGINE_DECOMPRESSION
  sudo restool dpdcei create --priority=1 --engine=DPDCEI_ENGINE_DECOMPRESSION

  sleep 1
  sudo restool dprc assign dprc.1 --child=dprc.2 --object=dpio.16 --plugged=1
  sudo restool dprc assign dprc.1 --child=dprc.2 --object=dpio.17 --plugged=1
  sudo restool dprc assign dprc.1 --child=dprc.2 --object=dpio.18 --plugged=1

  sudo restool dprc assign dprc.1 --child=dprc.2 --object=dpdcei.0 --plugged=1
  sudo restool dprc assign dprc.1 --child=dprc.2 --object=dpdcei.1 --plugged=1
  sudo restool dprc assign dprc.1 --child=dprc.2 --object=dpdcei.2 --plugged=1

  sudo restool dprc assign dprc.1 --child=dprc.2 --object=dpdcei.3 --plugged=1
  sudo restool dprc assign dprc.1 --child=dprc.2 --object=dpdcei.4 --plugged=1
  sudo restool dprc assign dprc.1 --child=dprc.2 --object=dpdcei.5 --plugged=1

and running "sudo restool dprc show dprc.2" returns

sudo restool dprc show dprc.2
dprc.2 contains 9 objects:
object        label        plugged-state
dpdcei.5            plugged
dpdcei.4            plugged
dpdcei.3            plugged
dpdcei.2            plugged
dpdcei.1            plugged
dpdcei.0            plugged
dpio.18                plugged
dpio.17                plugged
dpio.16                plugged

Now running the example:

sudo bin/dce-example dprc.2 dpio.16 dpdcei.0 dpdcei.5

I did find this error in syslog

Please use images from the same LSDK release.

Please download firmware image and Linux Kernel from LSDK 21.08 release.

$ wget https://www.nxp.com/lgfiles/sdk/lsdk2108/firmware_lx2160ardb_rev2_xspiboot.img

$ wget https://www.nxp.com/lgfiles/sdk/lsdk2108/boot_LS_arm64_lts_5.10.tgz

I think this maybe something in my kernel configuration, because just tried it on a dev box with a older OS and it works.

[yipingwang]

Please execute the following commands before executing dce-example.

root@localhost:~# echo vfio-fsl-mc > /sys/bus/fsl-mc/devices/dprc.2/driver_override
root@localhost:~# echo dprc.2 > /sys/bus/fsl-mc/drivers/vfio-fsl-mc/bind

Does dce_helper_swp_init depend on any kernel module?
